Frequently Asked Questions

Why compress a video to exactly 10MB?

10MB is the standard file upload threshold for Discord, Slack free workspaces, various government portal submissions, and job application forms.

How does the 10MB bitrate calculation work?

ClipShrink calculates: Total Bitrate = (9.4MB × 8192) / Duration. This guarantees the file finishes safely under 10.0MB.
